Installed SSD as 2nd drive - now I get a BIOS RAID screen

Dell 9200 desktop, WIN 7, 256GB hard drive, 128 GB SSD
Every time I boot the start up stops after showing both drives as non-RAID with a message to select CTRL I to run configuration program.
Two questions:
Can I / should I consider setting up these very differnet drives as RAID?
How can I stop that screen from appearing and slowing down boot up?
